The Rashtriya Ispat Nigam Limited, the corporate entity of Visakhapatnam Steel Plant, on Wednesday became the first steel plant in the country to launch a trend-setting project to generate power with green technology in collaboration with Japan from the Sinter Cooler Waste Heat Recovery Power Plant.

The project costing Rs.300 crore engages green technology at every stage of operation as part of MoU RINL signed with New Energy Industrial Technology Development Organisation (NEDO)-Japan Project. The plant will generate 20.6 MW.

“RINL has successfully implemented NEDO Model Project on sinter cooler waste heat recovery system under Green Aid Plan from our country,” Fumio Ueda, Executive Director of NEDO, told The Hindu .

“Power will be generated by using the waste heat without burning any fossil fuels. The project will reduce CO emissions to the extent of 2,20,616 tonnes annually,” said RINL Chairman-cum-Managing Director P. Madhusudan.

Godavari

Union Steel Secretary G. Mohan Kumar commissioned the green tech project after inaugurating the revamped Blast Furnace-1 Godavari.

The modernisation of the furnace was done with an investment of Rs.600 crore to raise the hot metal production by five lakh tonnes.

At present, the hot sinter is cooled by sinter blower fans and available energy lost to atmosphere.

The volume of the Blast Furnace-1 Godavari has been increased from 3,200 cum to 3,800 cum by introducing copper cooling plates and latest generation cast iron cooling plates in the place of existing normal cast iron cooling plates.

At the time of commissioning in 1991, Godavari was the largest BF with 3,200 cum volume and production capacity of 1.8 million tonne. It was due for relining after 16 years of operation or production of 25 million tonne.

However, it produced 37 million tonne of hot metal after being in operation for 23 years.

This could be achieved only due to good operational and maintenance practices being adopted by VSP collective, a RINL official said.
